Which term refers to the rate of data transfer measured in megabits per second?

The term that refers to the rate of data transfer measured in megabits per second is Mbps. In digital communications, data transfer rates are commonly represented in bits (not bytes), where one megabit is equal to one million bits. Mbps specifically indicates this rate, making it essential for understanding network bandwidth and internet speeds.

When evaluating the other options, MBps refers to megabytes per second, which is a different measurement that is larger than megabits. Kbps represents kilobits per second, a smaller unit than megabits. Gbps signifies gigabits per second, which is larger than megabits. Therefore, Mbps is the appropriate term that accurately conveys the concept of data transfer rate in megabits per second.
